I used the pro on my Trans am… had to remove it Coss… it moved so much fuel, but the pump boiled the gas… its meant for alot of full throttle. Does the GTR have a return fuel line ? If not, the issue may not apply. You may be able to get a controller to reduce voltage and pump speed like I have, but even in my case, i had to downgrade to the A1000 Eliminator.
BTW, Code Blue, thats a great price for the A1000.
